From ShoujoMagic:Story 1: Leave It to EmiriMiyasaka Emiri is in the third grade, and she's in love with the school doctor, Dr. Kawata. Can the power of love help her bridge a 14-year age difference - physically!?

It doesn't seem like an unusual story/manga in that a younger girl likes an older person. However, since this is the main story and the girl isn't even in her teens, the story is going to be dealt with differently than the usual "teen loves teacher/adult". The chance of her just being dumped is lessened significantly, but yet it seems weird for the girl to be with the guy she likes, who's old enough to easily be her father. What's the mangaka to do?

Spoilers regarding the ending:

Spoiler (highlight to view)

When the girl's brother uses the potion, it hits a whole new level of weird and "ewww". It would've been okay if he had done it for another girl but it's because he finds his sister in her older form hot? *shakes head* No, no, NO! I suppose the way the manga ended with the girl with the person she likes and that age gap, it was bound to be an odd manga from the start...
